Owen Lin 196964ef10 Preserve root turn attribution in turn-start events (#44611) ...

## Why

Persisted turn-start events lack the originating root turn ID, so they cannot directly associate child turns with the root turn that initiated them.

## What changed

- Add optional `root_turn_id` to `TurnStartedEvent`. Use the inherited root turn ID when available, otherwise the turn's own ID.
- Centralize turn-start emission for regular turns, shell commands, and manual compaction so they record attribution consistently.
- Carry attribution into `ThreadHistoryTurnChange` when processing turn-start events and retain it through completion in the history builder.
- Keep older records compatible by defaulting missing attribution to `None`.

## Testing

Add coverage for root and child turn attribution, persistence when tool collisions fail a turn before sampling, history change propagation, and deserialization of older turn-start records.
